The hdfs-site.xml property dfs.namenode.num.extra.edits.retained defaults to a value of 1000000 (1 million) Reducing this value will lower the number of edit logs retained after a checkpoint in complete.

Have you tried to retrieve the logs using the YARN CLI? yarn logs -applicationId <id of the application> This will stream back the aggregated log to the screen ... if you have access in HDFS to see the log files. You will see a message about aggregation not being enabled if you lack permissions to see the log files. In that case, modify the command to use the application owner. yarn logs -appOwner <user id> -applicationId <id of the application>

There is an odd environment variable used for the HBase configuration directory. Try setting HBASE_CONF_PATH=/etc/hbase/conf in your shell session and see if the timeout value gets picked up.

The incorrect status was caused by the contents of the zookeeper_server.pid file being out of sync with the running zookeeper process. Updating the file with the proper PID allowed the correct Zookeeper status to be displayed in Ambari.

I pulled the status and everything showed up as started! The Ambari agents and server were then cycled with no change in status.
